Specification of Letters Patent. 7 Patented Apr; 18, 1922.

Application filed June 19, 1918. Serial No. 241,070.

To all whom it may concern: 7

Be it known that I, ANroNE E. WOLTER, a citizen of the United States,residing at Olympia, in the county of Thurston and State of \Nashington,have invented a new and useful Improvement in'Race Knives, of which thefollowing is a specification.

This invention relates to new and useful improvements in race-knifeinstruments, and the object of this improvement is to provide,primarily, arace-knife susceptible of being utilized as one of theco-acting elements of a pair of dividers or spacing instruments, andwhich has a cutter member with a V-' shaped blade suitable for thecarving of grooves of an ornamental character in parts of furniture orthe like.

A further object resides in the adaptability of this combinationinstrument to have its respective parts pivotally attached at oneendupon a handle, whereby the same can be closed thereupon when not-Vinuse, for convenience in'carryingr I .The inventionconsists in the novelconstructio'n, adaptation and combination of. parts as will be moreclearly described in the following specification, illustrated in the ac:companying drawings, and finally pointed out, in the appended claim. 7

In the drawings, Figure l is an elevation of my combination instruments,Fig. 2 is a plan thereof, and Fig. 3 is a section of the pivotalattachment of the respective parts of the instrument upon ahandle.

Referring more particularly to the drawings, in which like referencenumerals indicate like parts, the numeral 1 represents a handle ofsuitable design and material upon which is pivotally attached at one enda pencil-holder 8 and a shank tool 2 having an extension 3 at an angleto the shank, and 'which extension has a flange bent up on a occasiondemands, or to serve as a guide or be maintained without variation.

I gage whereby the incline of the cutter may Both the pencil-holder andthe race-knife are carried by the pivot 9 upon the handle and this pivotis designed to have a portion thereof of squared contour 10 to engagethe correspondinglyshaped hole in the handle so that the pivot will beprecluded from turning when either the race-knife 0r pen- 7 oil-holderis actuated. The thumb-nut'll isprovided to regulate the degree offrictional contact desired to hold the respective instruments frommovement when set at a desired point. p 1

12' is a slot provided in the handle'l for the reception of the flangeportion 3 ofthe race-knife, and 13 is an elongated ,slot extendingrearwardlyto a predetermined position on the handle in alinement withthe slot 12. The provision of this latter slot is-to afford space-wayfor the closing of the race knife so thatthe flange 3 thereoflwill pro-1 ject within the slot 12, the blade portion 4.1- being protected fromcoming incontact with .thefsurface of the knife handle at the'side'opposite the slot 1 2and' being dulled, by the shank 2 abutting the endof the slot 13 as shown by. dotted linesinFig. 1.

In using the instrument, the blade shank is opened up to a positionwhereit can best be used and is fixed iii-this position by tight ening thenut11. The operator then grips the handle portion 1 and draws the cutterblade edge 4 against the piece being carved,

which may be wood or other material used in making ornamental parts offurniture, and thus carves grooves therein as desired.

What I claim is new, and desire to protect by Letters Patent, is r v Ina race knife, a handle body provided at one end with an elongated slotand adjacent its opposite end with an alined blade-receiving slot, aknife shank pivoted at its'inner V p I end within said elongated;slot,said shank havinganacute angled extension at its outer end forminga cutterlthat is movable into and from the receiving slot.

Signed by me at Seattle, Washington, this I 7th day of May, 1918. i l VY r ANTONE E. WOLTER.
